With the parent in attendance, I would poss do biosculpture nno.
I once had an 8 yr old girl in with her mother and grandmother who had just had her nails done in nss. I spent rather some time lecturing the two adults as you can imagine, explaining all the ins and outs, maintenance etc and also how nss salons differ from mine etc etc - they didn't give a sh't!
Oh, and she also had a head full of highlights! And high heels, mini skirt and skin tight top!
As you can imagine, I was horrified.
